NON-REFILLABLE BOTTLE.

Patented Oct. 9, 1906.

Application filed October 14, 1905. Serial 110.282.713-

and exact description of the invention, such as will enable others skilled in the art to'whichit appertains to make and, use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in non-refillable bottles, my object being to provide a thoroughly practicable construction adapted to prevent fraud by the refilling ofbottles that have once been used with goods inferior to the original contents.

My further object is to provide a device of this class which shall be exceedingly simple in construction and the cost of which shall be only slightly greater than that of the ordinary bottle.

My improved construction will be thoroughly understood by reference to the accompanying drawings, in which is illustrated an embodiment of the invention.

In the drawings, Figure 1 is'a vertical section of a bottle constructed in accordance with my improvement and equipped with the devices which make it impracticable to refill the same after its original contents have been discharged. In this figure the bottle is shown in the upright position with the plunger valve seated. Fig. 2 shows the bottle inverted, the direction of the flow of the esca ing liquid being indicated by the arrows. n

this view the plunger-valve is unseated. Fig.

3 is a cross-section taken through the bottleneck and plunger-valve. This section is taken on the line 3 3, Fi 1. Fig. 4 is a dotail view of the cap app ied to the outer extremity of the bbttle-ncck. Fig. 5 is a detail view of the plunger-valve. Fig. 6 is a fragmentary sectional view of the upper part of the bottle shown in detail or without the devices rendering the bottle non-refillable. Fig. 7 is a sectional View of abottle, showing another form of my improved construction. Fig. 8 is a view of the same, but with the bottle inverted to show the position of the valveplunger during the escape of th'e liquid from the bottle.

' The same reference characters indicate the same parts in all the views.

i Let the numeral 5 designate the body of the bottle, and 6 the neck thereof. The base of I the neck is provided with the interiorly-projecting shoulder or ledge 7, upon which rests a seat 8, referably composed of cork. 'Located witliin the bottle-neck and adapted to engage this seat is a plunger-valve '9, which, as shown in the drawings, has a conical extremity 10, adapted to engage a counterpart opening formed in the seat 8 when the bottle is in the upright position or that shown in Fig. 1. This plungervalve 9 is-provided with a body part extending beyond the valve part proper, 10, thus giving the device 9 sufficient weight to facilitate the removal of the liquid from the bottle-neck when the bottle is in use. This device 9, as shown in the drawings, is provided with longitudinal grooves 9 to permit the liquid to flow freely between the body of the lunger and the neck of the bottle when it is esired to remove the liquid therefromf In order to further facilitate the removal of the liquid and also in order to prevent excessive friction between the plunger and the neck of the bottle, the plunger is provided with a number ofpins or projections 9, which engage the interior surface of the bottle-neck, thus greatly reducing the friction and at the same time ermitting the necessary space to allow the plunger when the bottle is tipped to the proper position.

quid to flow freely around the The extremity of the plunger remote from the valve part 10 is provided with a recess 12. The plunger is also provided at its recessed end with lateral grooves 9 which register with the longitudinal grooves 9 allowing the liquid to pass freely from thespace surrounding the plunger into the recess 12 when the plunger is in the position shown in Fig. 2-01 when the bottle is inverted for the purpose of removing the liquid. 7

Attention is called to the fact that it is not necessary to completely invert the bottle, as shown in Fig. 2, in order to remove the liquid. The vertical inverted position is shown for convenience of illustration onl To the outer extremity of the bottle-neck is'applied a cap '13, having a circumferential groove 14, adapted to receive the upper extremity. 6 of the bottle-neck above a ledge or shoulder 6. The part of the cap 15 outside of the groove engages the ledge 6 of the neck, while the part 16 of the cap enters the bottle-neck. This part 16 is provided with an interior projectlon 17, adapted to enter the recess 12 ofthe plunger-valve when the latter is in the position shown in F g. 2. This cap has a small lon itudinal opening 18 for the escape of the liquid when the bottle is in use. small stopper 19 in order to seal hermetically the contents of the bottle.

The cap 13 is cemented to the bottle-neck, whereby it becomes virtually an integral part thereof, making it impossible to remove the'cap without breaking the neck. Hence it becomes impossible to refill the bottle without destroying the latter or mutilating it in such a manner as to render it valueless.

From the foregoing description the use of my improved device will be readily understood/ While filling the bottle with its original contents the bottle-neck is open, as shown in Fig. 6. As soon as the bottlehas been filled the cork seat 8 is inserted and caused to engage the ledge 7. Y The plunger-valve 9 is then dropped into place, after which the cap is applied in the manner heretofore stated.

The plunger-valve and cap 13 are preferably composed of glass. The small stopper 19 may also be of glass or cork.

Attention is ca led to the fact that in my improved construction it is not necessary to use any metal parts,; only glass and cork be ing required. This is an important feature,

since metal parts are extremely objectionable owmg to the fact that the liquid contents of the bottle are injured by coming in contact with the metal. The metal parts are usually corroded with thecontents of the bottle, thus features in'a ottle of this class. a

When it is desired to remove a portion of the contents of the bottle, the small plug 19 is removed from the cap, when the bottle may be tipped or tilted sufficiently to allow the plunger-valve to unseat, or assume the position shownin Fig. 2. The contents of the bottle may then be readily removed, the lhi quid flowing as indicated by the arrows in en it isdesired to eject the liquid in in termittent jets, the bottle is moved back and forth and suddenly stopped, thus causing the lunger-valve to reci rocate within the neck. very time this va ve moves forwardly it forcibly ejects the liquid between it and the cap'through the longitudinal opening 18 of the latter.

Assuming'that the bottle is inverted, or in This opening may be .closed by a prohibiting the use of metallic.

'tremity of the to refill the same by pressure the air and liquid entering the passage 18 will act upon the plun er-valve to seat the same before any liqui can be forced into the bottle. It is thus believed that it is practically an impossibility to reuse the bottle after its original contents have been discharged.

The cap 15 of the bottle is preferably provided with a cork washer A, forming a sort of cushion which the plunger engages when at its outward limit of movement in the bottleneck, thus preventing the possible breakage of the plunger by striking against the glass ca I fn the form of construction shown in Figs. 7 and 8 I will designate the valve-seat as 10 and the plunger-valve as 9 since these p arts differ somewhat in construction from those shown in the other views. The valve-seat 10 is preferably composed of cork, and its upper part is conical to enter a recess 12 formed in the adjacent extremity of the plunger-valve. The opposite extremity of the plunger-valve is also provided with a'recess 12, adapted toreceive'the short neck portion 17 of the cap 18. As this form of the device performs substantially the same .function as the other form of mechanism and opcrates in substantially the same way it need not be further described in detail. Attention is called to the fact that by virtue of the recess 12 or 12 in the outer extremity of the plunger a'quantity of liquid is always held by the plunger, and this liquid is discharged through the orifice of the cap during the first outward movement of the plunger during the 1process of emptying the bottle or discharging iquid therefrom. it is evident that after using a portion of the contents of the bottle and returning the latter to the upright position the recess in the outer extremity of the plunger will remain filled with liquid. This is an important feature in actual practice. My plunger-valve is a novel feature and serves not only to prevent the refilling of the bottle after it has been once emptied, but it also aids in emptying the bottle, since it has a limited reciprocating movement within the bottle-neck, which aids in ejecting the liquid. The discharge of the bottles contents is further accelerated by reason of the liquid-filled recess in the outer exlunger, whereby a small quantity of liquid is always in position to be immediately forced through the orificed cap during the first outward movement of the unseated plunger-valve. i 1 Having thus described my invention, What I claim is- 1.
